m0useanswered grow question 3 months ago If you have the option, have the fan only turn on when the RH/temps hit a triggered level. I set mine up to turn on low when the RH goes above 62% and then it turns off.
I also have a small tent fan on low pointing into a corner/wall just to have the air moving.
If not, set it on the lowest setting, you want a slower dry time. helps the curing process.
